[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] One of the preferred embodiments of the present application is as follows: Figure 1 As shown, a scheduling method for molding production tasks includes the following steps:

[0027] Project establishment: The project department will establish a relevant project team and formulate a development catalog based on the customer's project notification.

[0028] Design review: The project department selects professionals to conduct product analysis based on the development catalog and provides feedback to customers based on the results of the analysis. After the customer makes a request, the design is adjusted according to the customer's requirements and the product is analyzed again until it meets the customer's requirements.

[0029] Preliminary preparation: The outsourcing department purchases and stores raw materials and formulates processing plans based on the review results.

[0030] Production and processing: The production department implements the processing nodes based on the processing plan and performs workpiece processing; the project department, outsourcing department and production department track the entire processing process at the same time to facilitate timely handling of quality accidents.

[0031] Product testing: The quality department conducts quality inspection on the finished workpieces and requires rework for the workpieces that do not meet the quality requirements until all the workpieces meet the quality requirements and then assemble the test molds; based on the results of the test molds, the workpieces are improved on site to meet the requirements and submitted to the customer for confirmation through the project department.

[0032] It should be known that based on the above scheduling and planning process, this application provides a scheduling method based on actual production, which can reasonably arrange the production plan and provide feedback to customers at the specified time node. Compared with the traditional production process without definite planning and scheduling, the mold products required by customers can be completed with high efficiency and high quality. The specific content of the above workflow will be explained in detail below.

[0033] In this embodiment, Figure 1 As shown, the project establishment process includes the project initiation phase. In the project initiation phase, the project initiation notice is received from the customer, and a project management folder is established within the specified time after the communication with the customer is completed for project records. For ease of understanding, the specific process of the project initiation phase can be described in detail below.

[0034] Specifically, the project initiation phase mainly includes the written notification phase and the customer docking phase. In the written notification phase, the customer can connect with the project department through business methods such as email, phone or WeChat and issue a project initiation notice, and at the same time require the project department to provide an original quotation. The original quotation can refer to the price verification TSS table and the quotation summary table. For the customer docking phase, the project department replies to the customer's email and provides a project contact form. At the same time, the project department also simultaneously sets up a preliminary project team within the specified time based on the primary project information proposed by the customer, and then establishes a project management folder for storing and archiving project records.

[0035] It should be known that the cost time for the preliminary project team is generally established within 1 hour after the project starts, preferably within 0.5 hours. Since the establishment of the preliminary project team is relatively quick, and customer communication also takes time, the project department's communication with customers and the establishment of the preliminary project team can be carried out by different managers. One specific example is: Generally speaking, the management of the project department includes the project director and the project manager, so the project director can respond to the customer, and the project manager can set up the preliminary project team according to the customer's written notice. The project record can be in the form of word documents, pictures, PPT, etc.

[0036] In this embodiment, Figure 1 As shown in the figure, the project establishment stage also includes the project planning stage after the project initiation stage. In the project planning stage, the design plan, manufacturing plan and customer plan can be formulated in sequence, and the data and mold opening related materials can be locked according to the formulated plans to obtain the development directory recorded in the project management folder. For easy understanding, the specific process of the project planning stage can be described in detail below.

[0037] Specifically, for the formulation of the design plan, after the project department issues an order to establish a project design team, suitable designers will be selected to form the project design team within the specified time. At the same time, the project department and the production department can simultaneously complete the preparation of the project technical confirmation and development catalog to establish a mold manual.

[0038] It should be known that, based on the above example, the issuance of the instruction for the establishment of the project design team can be issued by the project manager, and the project design team needs to be established within 1-3 hours after the establishment of the preliminary project team, preferably within 2 hours. At the same time, the mold manual can be recorded and stored in the project management folder, and the establishment of the mold manual needs to be completed at least one day before the subsequent design review, so that the reviewers have enough time to complete the reading of the mold design manual.

[0039] Regarding the formulation of the manufacturing plan, after the project department issues an order to establish a project production team, appropriate production personnel are selected within the specified time to form the project production team and the personnel list is filled into the development directory to complete the production schedule.

[0040] It should be known that, based on the above example, the issuance of the order for the establishment of the project production team can be issued by the project manager, and the project production team needs to be established within 1-3 hours after the establishment of the preliminary project team, preferably within 2 hours. At the same time, the production schedule needs to be improved before the subsequent design review to ensure the integrity of the data.

[0041] For customer plans, the project department can combine the design schedule of the project design team and the production schedule of the project production team to prepare a plan schedule and report it to the customer within the specified time. At the same time, the internal members of each project team are improved and a project member framework is constructed to determine the rights and responsibilities during the project process.

[0042] It should be noted that, based on the above example, the formulation of the customer plan is completed by the project manager. The completion time of the planned schedule is generally completed within half a day, that is, within 12 hours, preferably within 2-8 hours.

[0043] For data locking, the project department can lock the data and related materials needed for mold opening according to the above-mentioned design schedule and production schedule. At the same time, the project design team needs to synchronously register the project data reception, and when any node that affects the delivery date occurs, it must be reported to the customer by email or other contact methods, and the node must be recorded in the project record sheet of the development catalog to complete the development catalog.

[0044] In this embodiment, Figure 1 As shown in the figure, the design review mainly includes the analysis stage, review stage and data locking stage. In the analysis stage, the structure, function, process and performance of the product are analyzed. In the review stage, the analysis results are modified through the review of both the enterprise and the customer until they meet the customer's requirements. In the data locking stage, the processing data of the product is determined according to the final review results of the customer and the enterprise. For easy understanding, the specific processes of the analysis stage, review stage and data locking stage can be described in detail below.

[0045] Specifically, Figure 1 As shown, the analysis phase includes product analysis and mold flow analysis.

[0046] Product analysis mainly includes the following processes: Preliminary determination of the injection position, number of points, structural direction, mold shape and machine model based on the product's function, appearance and matching requirements. Record the preliminary confirmed data, and propose unreasonable points based on the preliminary analysis to form a standard DFM report. The obtained DFM report is sent to the customer and reached an agreement with the customer within the specified time.

[0047] For ease of understanding, the product analysis process will be described in more detail below based on the aforementioned examples.

[0048] The project manager organizes the designers, process personnel and site managers to conduct product analysis and recognition meetings based on the nodes confirmed by the project manager. Through active communication among the participants, the mold's injection position, number of points, general structural direction, general mold shape, and several models are preliminarily determined based on the known conditions such as the product's function, appearance, and matching requirements. The members of the project design team need to conduct a preliminary analysis of the preliminarily determined parameters and propose unreasonable points to establish a standard DFM report. The project manager needs to report the DFM report to the customer via email or other communication methods and reach an agreement with the customer within the specified time. If there is a difference from the original quotation when the project manager communicates with the customer based on the DFM report and additional fees are required, a price verification data difference report needs to be submitted to the business department on the same day.

[0049] It is important to know that the record of the preliminary determined parameters is the prefix of the subsequent mold design book, so the record of the preliminary determined parameters needs to be clear and accurate. After obtaining the DFM report, the project manager needs to report to the customer within 1 day and reach an agreement based on the content of the report, preferably within 2-18 hours.

[0050] Mold flow analysis mainly includes the following processes: according to the nodes determined in the project establishment stage, various analyses are completed within the specified time according to the mold flow requirements to obtain a mold flow report; the obtained mold flow report is sent to the customer, and multiple mold flow reports need to be presented to the customer in the form of a comparison table; among them, the mold flow report must be a terminal solution with a terminal water channel that can be molded.

[0051] For ease of understanding, the mold flow analysis process will be described in more detail below based on the aforementioned examples.

[0052] The project manager issues mold flow analysis instructions based on the nodes determined by the project manager during the project establishment phase. The project design team will complete various analyses synchronously within the specified time according to the enterprise or industry mold flow requirements to obtain a mold flow report. The project manager then submits a mold flow node plan to the customer based on the mold flow report. The model node plan must be a terminal solution with water channels and mold manufacturing. At the same time, multiple reports must form a mold flow report comparison table, and the resulting mold flow report comparison table needs to be presented to the customer in the report and archived.

[0053] Specifically, Figure 1 As shown, the review stage includes internal review, customer review and re-evaluation.

[0054] Internal review mainly includes the following processes: organize relevant technical personnel of the enterprise to conduct an internal preliminary review of the terminal solution of the mold flow report according to customer requirements and enterprise standards; record and archive the results of the preliminary review and complete the mold calculation book, customer review form and mold design inspection standards.

[0055] For ease of understanding, the internal review process will be described in more detail below based on the aforementioned example.

[0056] According to the nodes determined by the project manager, the project manager organizes designers, on-site personnel and processing personnel (fitters) to conduct an internal preliminary review of the terminal solution of the mold flow report according to the customer's requirements and the company's own standards, and records the review results to obtain a mold review report and archive it in the review record folder. At the same time, complete the mold design book, customer review form and mold design inspection standards. It should be noted that if there is no special change in this review, the next review will be conducted within the specified time and will be mainly recorded in PPT. Generally speaking, the next review needs to be conducted within a week, preferably within 3-7 days.

[0057] For customer review, the main process includes the following: make an appointment with the customer based on the task node and communicate with the customer with relevant materials for internal review, and record the customer's review requirements to facilitate subsequent design adjustments.

[0058] For ease of understanding, the customer review process will be described in more detail below based on the aforementioned example.

[0059] The project manager will coordinate and communicate with the customer and make appointments with the customer according to the nodes determined by the project manager. At the same time, the project design team will work with the project department to improve the mold design inspection standards, DFM reports, design review reports, mold flow analysis reports, mold design books, review records and other data files. Then, the sorted and improved relevant materials will be taken to the designated location for design review with the customer. During the customer review process, the customer's review requirements, such as model and process requirements, will be recorded in detail on site. If there are any differences, they will be returned to the company and design adjustments will be made according to the customer's requirements.

[0060] The re-evaluation mainly includes the following process: organize relevant technical personnel to conduct a final internal review of the mold according to the customer's review requirements, and reply to the customer with the review results.

[0061] For ease of understanding, the review process will be described in more detail below based on the aforementioned examples.

[0062] According to the nodes determined by the project manager, the project manager organizes production personnel, designers, processing personnel and mold test personnel to conduct a final internal review of the mold according to the customer's review requirements and respond to the customer's final status. After completing the re-evaluation, the project manager can issue a cutting instruction to start product processing according to the customer and company's specifications, and the mold processing parameters will be locked at this time.

[0063] In this embodiment, Figure 1 As shown, before receiving the start-up instruction to start processing, preliminary preparations need to be made to purchase raw materials, etc. Specifically, it includes processing inquiry, material procurement, processing planning, material storage, and material outbound. For easy understanding, the following will combine the above examples to explain in detail the multiple stages of preliminary preparation.

[0064] Specifically, during the processing inquiry stage, the outsourcing department can verify the price, determine the location, and determine the period for various processing links based on the locked mold data, and obtain a processing price verification sheet.

[0065] In the material procurement stage, according to the mold material list submitted by the project design team, it is submitted to the procurement department for procurement implementation after approval by the production department and the company's general manager. The procurement staff submits the procurement plan to the warehouse, design department, production department and project department based on the mold material list, so that each department can track synchronously and collaboratively. The project manager organizes and handles changes in each link in a timely manner according to changes in the procurement process.

[0066] For the formulation of processing plans, the outsourcing department can prepare detailed processing schedules and production schedules based on the price verification results. At the same time, each department will work together to track the location, machine, machine time, estimated completion nodes, and actual nodes of the processing process. The project manager will organize and handle changes in each link in a timely manner according to changes in the process. Among them, the departments that need to be tracked in collaboration include the design department, project department, procurement department, production department, and quality department.

[0067] For material warehousing and delivery, the quality department and warehouse will inspect the size, appearance, hardness and other structures and delivery date of the raw materials purchased by the purchasing personnel according to the material list and fill out the inspection form before warehousing. After the completion of warehousing, it will be reported to the production department and project department. Raw materials that have passed the inspection of the quality department will be issued with material standard parts delivery orders and material collection orders, and can be claimed and shipped out after the signature and confirmation of the relevant person in charge.

[0068] In this embodiment, Figure 1 As shown, production and processing mainly include two stages: component processing and project control.

[0069] The component processing stage specifically includes two processes: processing and progress quality control. For the processing process, according to the previously specified processing plan, the project department, production department, outsourcing department and design department can synchronously monitor the data status of materials and processing in order to implement the various processing nodes specified in the early stage; the project manager promptly organizes and handles changes in each link according to changes in the process. For the progress quality control process, the project department, production department and outsourcing department synchronously monitor the processing progress; when there is a defective expedited process, each department will coordinate and fill out the quality accident handling form, and execute it with the ultimate goal of not affecting the final delivery date.

[0070] The project control phase specifically includes two processes: progress report communication and schedule update. The project manager reports to the client via email or other means on a weekly or agreed time basis; generally speaking, starting from the second week, the actual progress should be reported at least one week in advance; the progress status should be described in the body of the email report to the client, and the progress ratio of the updated schedule should be described.

[0071] In this embodiment, Figure 1As shown, product testing includes component testing, assembly and trial mold stage, and adjustment and improvement stage. In the component testing stage, the quality department prepares a test plan according to the processing plan, conducts quality inspection on the workpieces used to assemble the mold according to the formulated test plan, and issues an inspection report; qualified parts are put into storage, and a defective part handling report is required for unqualified parts; the quality department issues a quality accident handling unit to the production department and the outsourcing department according to the defective part handling report and requires rework. In the assembly and trial mold stage, after completing the preparation work before the trial mold, the production department provides the new product trial mold process sheet to the project department within the specified time; the project department submits a mold construction application to the production department within the specified time according to customer needs and records it, and obtains the trial mold plan statistics table; according to the trial mold plan statistics table, the scientific trial mold process sheet is simultaneously provided to the site, and after approval, the production department prepares for the trial mold according to the trial mold regulations; after completing the trial mold, the project department packs the samples according to the customer's requirements and arranges for shipment. For samples that are not requested or have quality problems, written confirmation with the customer is required to arrange packaging and shipment after acceptance. During the adjustment and improvement stage, according to the problems encountered during the mold trial and the customer's design change requirements, the project department organizes the production department and the project design team to provide a mold design change analysis report within the specified time and send it to the customer for confirmation; after the customer's confirmation, the project department issues a change order to the production department and the project design team to make the design change; before making the design change, evidence is retained and after the design change is completed, it is submitted to the customer for confirmation to complete the product lock.

[0072] For ease of understanding, the following will describe in detail each stage of product testing in conjunction with the aforementioned examples.

[0073] Specifically, Figure 1 As shown in the figure, the component inspection stage mainly includes the steps of formulation of inspection plan, workpiece inspection, rework of defective parts and warehousing of qualified parts.

[0074] Regarding the formulation of component inspection plans, the quality department can prepare inspection plans based on the previous processing plans, and report the prepared inspection plans to the production department, project department, and outsourcing department.

[0075] For the workpiece inspection process, the quality department inspects the finished workpiece according to various inspection standards and issues an inspection report; the inspection report is delivered to the production department, procurement department, design department and project department; for unqualified parts, a defective parts handling report needs to be filled out, and they are not allowed to flow into the next process without approval. For the inspection of the quality department, the slider, straight top, inclined top and electrode-related structures that make up the mold are mandatory inspection items, and the parting surface of the mold is also a mandatory inspection item. Standard parts can be sampled according to actual conditions.

[0076] For the defective product rework and qualified product storage process, the quality personnel will issue a quality accident handling form and hand it over to the person in charge of the production department, the outsourcing department and the quality department. Only after all parts have passed the inspection can they be stored in order to facilitate subsequent shipment.

[0077] Specifically, Figure 1 As shown in the figure, the assembly and trial mold stage mainly includes the steps of assembly and mold assembly, trial mold inspection, trial mold application and delivery and sample delivery.

[0078] For the assembly and mold making process, assembly case sharing and training, as well as identification of the assembly sequence and other learning processes are required before assembly; then the workpieces that have completed the inspection are assembled to obtain the mold products required for the test.

[0079] For the mold trial inspection process, before the mold trial, it is necessary to check the mold's circuit, gas circuit, water circuit and action path and fill in the initial inspection form for confirmation, and then complete the relevant preparations in accordance with the mold trial regulations.

[0080] In principle, the production department needs to submit a new product mold test process sheet to the project department one working day in advance during the mold test application process. Then, based on customer needs, the project manager should, in principle, submit a mold construction order application to the production department at least three working days in advance, and record the mold test plan and mold test statistics table in the archives, and the purpose of each mold test should be noted when recording. At the same time, the project department will provide a scientific mold test process sheet to the mold test site, and prepare mold test related matters according to the mold test regulations after approval by the relevant person in charge.

[0081] During the delivery and sample delivery process, the project department will isolate and package the products to ensure that the samples are not damaged during the shipment process. Then, according to the customer's requirements, the packaging boxes are labeled and packaged for shipment. According to the on-site conditions, the project manager will inform the customer of the shipping information through email, WeChat or other communication methods and register it in the file. If there are samples that are unclear or have quality problems, it is necessary to confirm the customer's acceptance in writing before packaging and shipment.

[0082] It should be noted that if Figure 1 As shown, during the assembly and mold trial stage, it is also necessary to confirm the problem points, that is, to confirm the problem points in the mold trial process. Specifically, the mold trial must undergo a comprehensive test of short shot, sample delivery and destruction and record it, and a mold trial tracking table can be obtained. Then the project department uses the destructive sample as the mold repair part to confirm the problem and fill out the mold trial problem sheet and hand it over to the production department; the production department completes the mold trial problem sheet within the specified time for subsequent adjustments and improvements.

[0083] It should be known that the production department generally completes the mold trial problem sheet within half a working day, that is, within 12 hours, preferably within 4-12 hours. When problems occur during the mold trial, the problem points are strictly handled in accordance with the event escalation regulations, and the contents of the event escalation regulations table are implemented; the project manager needs to sign for the delivery of samples and the final sealed samples on site, and post the first and last sealed sample labels. The samples with labels are sealed and stored in the warehouse, and the surface samples need to be compromised and the key points of qualified areas are indicated.

[0084] Specifically, Figure 1 As shown, the adjustment and improvement phase mainly includes the steps of problem point adjustment, change analysis, change confirmation and product locking.

[0085] Regarding the problem point adjustment process, the on-site adjustment of each problem point is implemented according to the mold trial problem list and the event escalation regulations table.

[0086] For the change analysis process, the project manager organizes the production department and the design department to provide a standard mold design change analysis report based on the customer's design change requirements; the mold design change analysis report is generally completed within 1 week, preferably completed and submitted within 1-8 working days. After the design change is confirmed and approved, the project manager issues a change order to the design department and the production department to initiate the design change.

[0087] For the change confirmation process, it is necessary to retain evidence before making design changes; after the change, the mold trial should be tested and confirmed before the mold trial, and after the mold trial is completed, it should be tested and confirmed, and the contents of the change order should be improved until it meets the customer's design change requirements and submitted to the customer.

[0088] It is important to know that the products produced by the mold can be divided into plain boards, leather-grained parts and non-appearance parts according to their appearance. During the product locking process, the project manager will label the first and last pieces of plain boards or leather-grained parts approved by the customer for storage and warehousing. The project manager can also label the first and last pieces of non-appearance parts that have been confirmed by the customer for gradient sealing and warehousing. Sealing and warehousing of products produced by the mold is generally carried out within six months to one year after the mold is shipped out of the warehouse.

[0089] In this embodiment, Figure 1As shown in the figure, after the product testing is completed, the product needs to be shipped out. The product shipping stage mainly includes two stages: shipping acceptance and service tracking. In the shipping acceptance stage, the project department urges other departments to improve the mold manual and conduct internal and customer acceptance of the mold within the specified time, and then ships the mold out of the warehouse to the customer's location for signing. In the service tracking stage, when the customer conducts trial production on the signed mold, the project department needs to go to the enterprise site for trial production tracking. For easy understanding, the following can be combined with the above examples to explain the two stages of shipping acceptance and service tracking in detail.

[0090] Specifically, in the acceptance and delivery stage, the main steps include data collation, internal acceptance, customer acceptance, mold delivery, and mold receipt. For the data collation process, the project manager supervises the relevant departments to improve the mold manual and archive it; the improvement of the mold manual is generally completed within one week before the mold is delivered. For the internal acceptance process, the project manager organizes relevant personnel to complete the various tasks of the mold pre-acceptance form within the company, and conducts action disassembly and inspection on site. For the customer acceptance process, the project manager cooperates with the customer according to the progress of the project, and conducts training according to the customer's requirements, supervises the completion of various acceptance tasks on site, implements and confirms the order with the customer in advance. For mold delivery, after the mold is accepted, the project department fills in the mold delivery application form and the mold shipping order, and delivers it after approval by the relevant person in charge; the shipment of the mold requires a shipping list, and a scientific mold trial report that conforms to the actual machine on the production site is submitted to the mass production customer at the same time. For the mold receipt process, after the mold arrives at the destination after delivery, it needs to be stamped and signed back on the mold shipping order, and then handed over to the general manager's office for storage and filing.

[0091] Specifically, the service tracking stage mainly includes trial production tracking, production tracking, and experience summary. For the trial production tracking process, the project department confirms and locks the customer's trial production node; if the customer is far away, it is necessary to fill out a travel application form in advance at a specified time, and coordinate with the production department to arrange related work after approval; among them, the on-site service personnel must have an after-sales service form signed by the customer on site to clarify the responsibility points and related results. For the production tracking process, synchronize the trial mold tracking, and increase the daily contact and concern of the project after the mold is shipped out. For the experience summary process, all project-related materials are sorted, archived, and summarized.
